Choosing the Perfect Home EV Charger: Types and Installation Tips

With the rapid growth of the electric vehicle (EV) market, the need for efficient charging solutions has become even more apparent. It is therefore important to choose a suitable home EV charging that not only offers convenience but also maximizes the performance of your EV. This article provides comprehensive guidance on how to select the best EV charger for your specific needs and vehicle technical requirements.

What is Electric Vehicle Charging

Electric Vehicle (EV) charging is the process of replenishing an EV’s battery by transferring electrical energy from a power source to the vehicle. Similar to refueling a gasoline car, but instead of liquid fuel, an electric charger supplies electricity. The speed and complexity of this process vary based on the type of charger and the available infrastructure.

Types of EV Chargers

  • Level 1 Chargers: These chargers use a standard 120-volt outlet, which is readily available in most homes. Although they charge slowly, providing about 4-5 miles per hour, they are suitable for overnight charging vehicles with smaller battery capacities.
  • Level 2 Chargers: Requiring a 240-volt outlet, these chargers are more complex and can charge an EV significantly faster, offering between 12 and 80 miles of range per hour. They are ideal for individuals with longer commutes or those who frequently use their vehicle throughout the day.
  • Fast Chargers: These are also known as DC fast chargers and provide a rapid charge for EVs, typically delivering 80-100 miles of range in just 20 minutes. However, due to their high cost and the high-power requirements, they are uncommon in residential settings.

Charging Speeds

The choice of charging speed will largely depend on the user’s daily driving patterns. While Level 1 charging might suffice for minimal daily use, Level 2 chargers are more aligned with the needs of average to heavy drivers due to their faster charging capabilities.

Assessing Your Needs

  1. Analyzing Your Driving Patterns

A detailed analysis of your regular driving patterns is essential in determining the most suitable EV charger for your home. This involves evaluating several key factors:

  • Daily Mileage: Consider the average distance you drive each day. If your daily commute is relatively short, a Level 1 charger, which provides around 4-5 miles of range per hour, may suffice. However, for longer daily commutes or frequent use throughout the day, a Level 2 charger, which offers 12-80 miles of range per hour, would be more appropriate.
  • Frequency of Long Trips: If you often take longer trips, it is crucial to ensure your EV can be fully charged in a reasonable time frame. A Level 2 charger is more suited for this purpose, as it significantly reduces charging time compared to a Level 1 charger.
  • Usual Downtime of the Vehicle: Assess the amount of time your vehicle is typically parked and available for charging. For instance, if your vehicle is parked overnight, even a slower Level 1 charger might be sufficient to recharge the battery fully by morning. Conversely, if you need to charge your vehicle quickly during shorter periods, a Level 2 charger would be more beneficial.
  1. Vehicle Specifications

Matching the charger to your vehicle’s capabilities is crucial to ensure efficient and effective charging. Key considerations include:

  • Maximum Charge Rate: Each EV has a specified maximum charge rate, which is the highest power level the vehicle can accept. Selecting a charger that aligns with this maximum rate ensures you are not underutilizing the vehicle’s charging capacity. For example, if your EV supports a maximum charge rate of 7.2 kW, a Level 2 charger that delivers up to 7.2 kW would be ideal. Using a charger with a lower output would result in slower charging times, whereas a higher output would not speed up charging and could be unnecessary.
  • Onboard Charger Capacity: The onboard charger in your EV converts the alternating current (AC) from the charger to direct current (DC) to store in the battery. The capacity of this onboard charger dictates how quickly the vehicle can charge. Understanding your EV’s onboard charger capacity helps in choosing a compatible home charger.
  • Battery Size: Larger battery capacities generally require more time to charge. Therefore, vehicles with larger batteries benefit more from the faster charging speeds provided by Level 2 chargers. This ensures that even large batteries can be fully recharged within a reasonable timeframe.

Choosing the Right EV Charger

  1. Features to Look for

When selecting an EV charger, consider adjustable amperage settings for flexible power management, smart connectivity features for remote control and monitoring, and essential safety features like overcurrent and ground fault protection. Ensure the charger has adequate cable length and convenient storage options, and check for ease of installation, whether DIY or professional.

  1. Cost Analysis

Evaluate the cost of an EV charger by considering the initial purchase price and installation expenses, which may include electrical upgrades and professional labor. Long-term savings from reduced fuel costs and potential utility bill reductions via smart scheduling should be factored in. Additionally, investigate available incentives and rebates, as these can significantly offset costs. Consider how installing a charger might increase your property value and remember to include total cost of ownership, accounting for ongoing operational costs and future upgrades, in your decision-making process.

Installation Considerations

  1. Electrical Requirements

The installation of a Level 2 charger often necessitates an upgrade to the home’s electrical infrastructure. This might include adding a new circuit and a high-capacity breaker to the existing electrical panel. This process should be executed by a licensed electrician to ensure it meets local building codes and safety standards.

  1. Physical Installation

Considerations for charger placement include proximity to the main electrical panel to minimize installation costs, ease of access for the vehicle, and potential exposure to environmental factors. Outdoor installations may require additional weatherproofing measures.


Choosing the right EV charger involves a balance of technical compatibility, personal needs, and economic factors.
